MACHINERY FOR TRELBLING SINGLE STRANDS OF THREAD.

Specification of Letters Patent No. 24,615, dated July 5, 1859.,

To all whom it may concern:

Be it known that I, Mier-rm. Cammina, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful machine for the arranging of silk in triple strands preparatory to its being made into twist for using on sewingmachines, and do hereby declare the following to be a full and exact description of the same, reference being had to the anneXed drawings, making a part of this speci fication, in which- Figure l is a top view of my machine and Fig. 2 is the clasp A, detached.

In Fig. l B is the bobbin containing the single silk thread; C the bobbin containing the thread when tripled.

D D D is the car. E is a bell shaped pulley connected by a compound lever G G G with a handle F. H Il is a fork connected by a lever with a handle J. The whole of this car D D I) moves upon a railway K K K K.

L is a vertical piece carrying in its upper extremity an eye or opening through which the silk passes from the bobbin B. This opening` or eye should be lined with glass or its equivalent, for if it was of steel or like substance, the silk passing through would soon cut it. M is a small weight hooked upon the silk as it passes from the bobbin B to the bobbin C after having been tripled. A is a clasp, the object of which to equalize the thickness of the twist. Fig. 2 shows this clasp enlarged. Any form will answer equally well as the one shown in the drawings. In order to prevent its being cut by the thread it should be lined with glass or other suitable substance.

O O O are four pulleys. Over this a belt passes being connected with the car I) D D as shown in the ligure. On the shaft P P is a wheel or a suitable contrivance to drive the bobbin C, either by friction or any other suitable method. The shaft is so arranged by means of catches that it only revolves in one direction and that only when the car approaches the bobbin B. When the car recedes the pulleys O O revolve while the shaft P P remains stationary.

Q Q is a movable cross piece carrying upon its lower surface a hook through which the silk passes, after it is tripled, to the bobbin C. This cross piece is connected with the car D D D so that as the car recedes it will pass over the shaft L and release the silk, as the car approaches the cross piece is drawn back by means of two weights R R.

Having thus described my machine I will now describe the method of operating it. It must first be adjusted which is done as follows. I take the thread of the bobbin B-put it through the eye in the piece L then bring the thread over to the bobbin C double it back and pass the loop thus formed over the bell shape pulley E (the car being drawn back the entire distance the fork being raised, and the bell shaped pulley being also raised) pass the three thicknesses of thread through the hook on the cross piece Q Q, then through the clasp A and fasten the ends upon the bobbin C. Hook the weight M on the tripled thread and the machine is ready for use. The bell pulley is first lowered by the handle F-. H H is then lowered by its handle taking the thread olf the bell pulley. The car is then made to approach the bobbin B. By means of the belts the shaft P P is made to revolve and consequently the slack thread is wound on the bobbin C. The next operation is to raise the bell pulley E which takes the thread upon it. This pulley is finished with a slight projection upon its edge. The car is drawn back a short distance and the fork is then raised. Then it is drawn back the full distance and the same operation is repeated.

By this machine threads are tripled from one spool or bobbin and without knots. An even twist is thus produced. If the three threads were used from three bobbins instead of one an uneven twist would be produced on account of the ditliculty of getting spools of thread of even thickness. Any number of bobbins may be used in place of the one B by furnishing the car D D D with a corresponding number of forks and bell pulleys-and by providing a corresponding number of bobbins on which to wind the threads when tripled. One operation of the car and the handles will work any number of threads. By the car being made to move a distance of twenty-five feet, the loops only occur at that distance.

I do not claim the car singly, as I am The fork piece L arranged and o erating substantially as above descrlbed or preparing silk for making twist.
